Of all the great archaeological sites around the world, I suspect the one near my hometown, Cahokia Mounds State Historic Site, is among the least appreciated. While the rich floodplain along the Mississippi River south of Alton, Illinois (known as the American Bottom) has a long history of human settlements, around the year 1050 a new community sprung up that would grow into the largest pre-Colombian settlement in North America, what we now call Cahokia Mounds. In this episode, I talk with Dr. Julie Zimmerman about how Cahokia grew into such a large and important city. We talk about the immigrants who migrated into Cahokia and what their daily lives might have been like, as well as how the community was connected to other indigenous people in North America. Julie theorizes that storytelling was the primary factor that attracted so many people into Cahokia, and she describes what we know about a couple of the stories that were likely the centerpiece of Mississippian beliefs. Julie offers her insights into the factors that may have led to the eventual decline and depopulation of the city, although Mississippian people and culture didn’t go away, they just spread out. We finish with a discussion of the role of contemporary Native American communities in the interpretation and preservation of the site. In the introduction, I offer a couple of tips for making a visit to Cahokia richer and more meaningful.

The lower half of the Mississippi grows to an immense scale that is hard to comprehend until you’re sitting on a small boat in the middle of it. In this season of the Mississippi Valley Traveler podcast, we’re going to go deeper into that world, of the lower Mississippi. We’re kicking off this new season with an episode where we dive into the ecology of the lower River. Long-time fisheries biologist Jack Killgore takes us through the past and present of the lower river’s world. We talk about the lower Mississippi before engineers began to remake it, then talk about how human engineering has altered the lower river’s ecology. He describes the significance of the 2,000 miles of uninterrupted channel that run down the Missouri and Mississippi Rivers, and describes work in progress to restore ecosystems harmed by river engineering. We finish with a description of the fish the river sustains, with an emphasis on the big ones, such as sturgeon, paddlefish, and alligator gar, as well as the problems posed by invasive carp.
